我无法从mysql数据库将多行转换成数组?我有代码，但是当我返回文本框时它没有显示所有行?

<?php 
if(is_array($_SESSION['pid']))
{
  $pid = join(',',$_SESSION['pid']); 
  $result=mysql_query("SELECT id AS wid FROM mywishlist where pid='$pid'") 
            or die("Id    Problem"."<br/><br/>".mysql_error());
  $results= array();
  $i=0; // add the new line
  while($row=mysql_fetch_array($result)){
    $results[$i] = $row['wid'];
    $i++;
  }
  $results;
}
$max=count($results);
for($j=0; $j<$max; $j++)
{
?>
<input type="text" name="wid[]" value="<?php echo $results[$j]; ?>" />
<?php } ?>

3 个解决方案

#1

The line join(',',$_SESSION['pid']) makes me think that you want to select multiple rows by their pid. Try to make use of IN operator:

行连接('、'、$_SESSION['pid'])使我认为您希望通过它们的pid选择多个行。尝试利用IN算子:

SELECT id AS wid FROM mywishlist
WHERE pid IN ($pid)

#2

Try

试一试

$results= array();

while($row=mysql_fetch_array($result))
{
    $results[] = $row['wid'];
}

And For Loop as.

和For循环。

$max = count($results);
for($j=0; $j<$max; $j++)
{
?>
    <input type="text" name="wid[]" value="<?php echo $results[$j]; ?>" />
<?php
}
?>

your query is wrong, use this query

您的查询是错误的，请使用此查询

$result=mysql_query("SELECT id AS wid FROM mywishlist where pid IN($pid) ")
